how do we balance and chemical equation
Anonymous:
you have to make the no. of atoms of each element equal on both sides.
use permutation & combination or algebraic method
combination not amp

they r 4 steps mainly
1)write the equation with the correct chemical formulae for each reactant and product
2)after writing the molecular formulae of the substances the equation is to be balanced for this we should not touch the ratio of atoms in the molecules of the substance but we may put suitable numbers as a coefficients brfore the formulae
3)sometimes there is a possibility that the coefficients of all the substances getting divided with a suitable number. since we require lowest ratio of coefficients for reactants and products
4)verify the equation for the balancing of atoms on both sides of the equation
i hope it helps u☺

eg.
Zn+ HCl => ZnCl2 + H2
a. Zn + b. Cl. => c. ZnCl2 + d. H2
let a be 1
For zinc.
1×a = 1×c
1×1 = 1× c
1 = c
For Cl
1×b = 2× c
b = 2×1
b= 2
so
Zn + 2HCl = ZnCl2 + H2
1 atom of zinc
2 atoms of chlorine
2 atoms of Hydrogen
Therefore it is balanced
Hope it helps u
If u face any problems u can comment on this answer i will send u the solution.
